Embodiment Construction

[0044] figure 1 A schematic diagram of a thermometer 1 of the invention is shown. The thermometer 1 comprises a temperature sensor 2 with at least one sensor element 3 by means of which the temperature T of the medium can be determined m . In this case, for example, resistance elements or thermocouples may be involved. However, the invention is not limited to a particular thermometer type, but is applicable to a large number of thermometers. The sensor element 3 is connected to the electronics unit 4 by means of at least two connecting cables 10 . This is also commonly referred to as the transmitter. The electronics unit 4 comprises an input unit 5 into which an operator can input at least one comparison temperature T of at least one comparison medium c and / or tolerance range ΔT tol . Furthermore, the electronics unit 4 comprises a memory unit 6 in which, inter alia, a comparison temperature T can be stored c and / or tolerance range ΔT tol . In this embodiment, the el...

Abstract

The invention relates to a device (1) for determining and / or monitoring the temperature of a medium, comprising at least one temperature sensor (2) with at least one sensor element (3) and an electronics unit (4), wherein the electronics unit (4 ) has at least an input unit (5), and the input unit (5) is at least used to input at least one comparison temperature (T c ) and / or at least one comparative temperature (T c ) of at least one tolerance range (ΔT tol ), and includes a display unit (7), wherein the electronic unit (4) is designed to determine and / or monitor the temperature of the medium (T m ), and wherein the electronic unit (4) is designed to detect whether the temperature sensor (2) is at least partially immersed in a c ) in at least one comparison medium, and with the temperature sensor (2) immersed in the comparison medium, a comparison measurement is performed to calibrate and / or verify the sensor element (3), by means of which the received signal to compare temperature measurements (T cm ) to determine the measurement of the temperature of the comparison medium, and by means of the display unit (7) to display the execution of the comparison measurement and / or the comparison temperature measurement (T cm ).

Description

technical field [0001] The invention relates to a device for determining and / or monitoring the temperature of a medium, comprising at least one temperature sensor with at least one sensor element, and an electronics unit. Furthermore, the invention relates to methods for calibrating and / or validating such devices. Background technique [0002] In the most varied embodiments, thermometers are known from the prior art. Thus, there are thermometers which use the expansion of liquids, gases or solids with a known coefficient of thermal expansion for measuring temperature, or also thermometers which relate the electrical conductivity of a material to temperature, for example using resistive elements or thermocouples. In contrast, in the case of pyrometers, the thermal radiation of a substance is used to determine the temperature. Various basic measurement principles have been described in numerous publications. [0003] Calibration and / or verification of thermometers is usuall...
